- Improved unit test reliability on MacOS and Linux.
- Improved unit tests for account functions to include parameter filters on mock assertions.
- Added `Get-CosmosDbAccountConnectionString` function for retrieving the connection strings
of an existing account in Azure - fixes [Issue #163](https://github.com/PlagueHO/CosmosDB/issues/163).
This function is not currently working due to an issue with the Microsoft\DocumentDB provider
in Azure - see [this issue](https://github.com/Azure/azure-powershell/issues/3650) for more information.
- Fixed 'Unable to find type \[Microsoft.PowerShell.Commands.HttpResponseException\]' exception
being thrown in `Invoke-CosmosDbRequest` when error is returned by Cosmos DB in PowerShell 5.x
or earlier - fixes [Issue #186](https://github.com/PlagueHO/CosmosDB/issues/186).
- Split unit and integration test execution in CI process so that integration tests do
not run when unit tests fail - fixes [Issue #184](https://github.com/PlagueHO/CosmosDB/issues/184).
